GRATE.

ESPECIFICATION forming part of Letters Patent No. 313,697, dated Marchl0, 1885.

Application filed March 18, 1854.

To a/ZZ whom, t may concern,.- i

Be it known that I, RICHARD WALKER, of Batavia, in the county of Geneseeand State of New York, have invented a new and useful Improvement inStove Grates, of which the following is a specification.

My invention relates to an improved adjustable and false wall for thegrates of cooking stoves and ranges, whereby the tire-pot or fuelholdingspace maybe lessened in size when it is desired to use a small fire.

My invention consists of a removable false wall for stove-grates whichcan be adjusted to the size of the tire-pot, and which will concen tratethe draft on the fire and exclude cold air from the stove, as will behereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectionalelevation of a stove provided with my improvement. Fig. 2 is ahorizontal section on line x x, Fig. l. Fig. 3 is a verticalcross-section on line y y, Fig. l. Fig. 4 is a perspective view of thefalse wall or partition removed from the stove, and on an enlargedscale. Fig. 5 is an end elevation ofthe removable false wall.

Like letters of reference denote like parts in the several figures.

A represents the top, and a a the side walls, ofa stove, and B thegrate, arranged in the iirepot G in a well-known manner.

D represents an upright division-wall, which is composed of two plates,d d', one of which, d, is cut away at d2, and provided with a bolt, di,in such cut-out portion. The outer plate, d, is fitted against thecut-out portion di of the part d, and is provided with a horizontalslot, d, through which the bolt cl3 passes. The two plates d d of theupright division-wall are movable one upon the other and laterally adjustable by means of the Vbolt d3, sliding in the slot di, and can bedrawn out or contracted to adjust the division-wall D to the width ofthe fire-pot. The two plates c Z d of the wall D are provided at theirlower edges with down wardly-projecting teeth d5, which rest on thegrate and support the wall D at a suitable height above the same.

F is a horizontal deliecting-plate extending (No model.)

` from the foot of the upright wall D and form` 5o ing a shield toexclude air from that portion of the iire-pot which is not in use. Thisplate F is composed of two parts, f f formed integral,

respectively, with the plates d d of the wall D,

and the part f is partly cutaway, and the part f laps over this cut-outportion, thus forming a coveredjoint corresponding with the joint of theplates d d of the wall D. The partsff of the plate F are formed withvertical side walls, ff, which extend downwardly and rest 6o upon thegrate B. The upright wall D and the horizontal deiiecting-plate F beingformed in one piece, it is obvious that any lateral move ment of theplates d d of the wall D will also adjust the parts ff of the plate F. Grepresents an adjustable extension of the delieeting-plate F,formed oftwo parts, g g', one

of which overlaps the other, and is provided with a lateral slot, g2,through which projects a vertical bolt, g3, which is secured to thelower 7c part, whereby lateral adjustment is effected when the wall D isdrawn out or contracted in adjusting it to the width of the iire-pot.The

inner sides of the parts g g of the extension G fit Lindertriangular-shaped lugs formed on the 7 5 wall D above the horizontalplate F, and by means of these lugs and plate F the extension G is heldrinly down upon the grate B. By

adjusting the extension G lengthwise on the plate F the length of thedevice can be in- 8c creased or reduced to cover a greater or lessportion of the grate, as may be desired. The defiecting-plate F andextension G cover that portion of the fire-pot O which is not in use,-and substantially prevent the admission of air into the stove exceptthrough the re. The draft passes through the entire length of the grate.That portion of the air which enters through the grate below the platesF and G is deflected through the grating d5 into the fire 9c and assistsin supporting combustion. My improved false wall therefore directs acopious volume of fresh air to the fire without cooling the stove, andsupplies ready means for regulating the size of the fire to therequirements, thereby effecting an important saving in fuel and avoidingoverheating the apartment in which the cookingstove is located.

I claim as my inventiony 1. The combination, with the upright di-Etvision- Wall D, of the horizontal deilecting-plate Fand side and endsupports, f2 f3 d5, whereby 5 the plate is held above the grate, therebyforining an air-passage underneath the horizontal plate F, by which theair entering below said plate is conducted to the fire, substantially asset forth;

Io 2. The combination, with the division-Wall D and deflecting-platevReach composed of two parts adjustably secured together, oftheadjustable extension G, composed of two parts adjustably securedtogether, substantially as I 5 set forth.

yposed of two parts, gg', which overlap the delecting-plate F, and whichare adj ustably secured together, substantially as set forth.

In testimony whereof I have hereunto signed my name this 11th day ofMarch, 1884.

RICHARD WALKER,

In presence of- F. L. BRowNE, J No. J. BONNER.
